I sort of guessed his grandfather based on the fact that his father is called William Bellion Jr. But he has stated that he has Italian ancestry, so no matter what, we can be certain on that part of his ancestry.

You’re gonna have to explain a little here. According to the trail I followed, Jon’s great-grandmother Bellion was named Lucy, and she was Italian. Did you find a different source? I’m not completely certain on what I found myself, so that would be welcomed.

I believe that Anna is from his William’s side. I have found another census with the same name. But same relative Gertrude Bellion as the other one here: It says Anna Bellion was born in Canada also here. https://familysearch.org/ark:/61903/1:1:MJR7-YQ9
